When opening the volume control / audio menu in the system menu bar I sometimes see "Apple TV" among the possible audio sinks. I don't own an Apple TV nor does one exist on my network so I'm assuming it's detecting a neighbor's device using Bluetooth. I've selected it twice accidentally while typing this.
The device also shows up in the display selection menu. I guess it will ask me for a verification code if I select it, but it's kind of uncomfortable to feel like I could start broadcasting my screen at any time by mistake (even if it isn't possible).
Is it possible to make macOS (10.14.3) stop displaying devices I don't own and aren't paired with?
